	OWL Web Ontology Language Use Cases and Requirements
		Ontologies figure prominently in the emerging Semantic Web as a way of representing the semantics of documents and enabling the semantics to be used by web applications and intelligent agents.
		Thus, an ontology language will be used to describe the characteristics of devices, the means of access to such devices, the policy established by the owner for use of a device, and other technical constraints and requirements that affect incorporating a device into a ubiquitous computing network.
		Ontologies may need to change because there were errors in prior versions, because a new way of modeling the domain is preferred, or because new terminology has been created (e.g., as the result of the invention of new technology).

	Web Ontology Language - Wikipedia, the free encyclopedia
		The OWL specification is maintained by the World Wide Web Consortium (W3C).
		Others believe that the order was chosen in honor of the character Owl from Winnie the Pooh, who wrote his name WOL instead of OWL.
		In truth, OWL was proposed as an acronym that would be easily pronounced, yield good logos, suggest wisdom and honor Bill Martin's One World Language KR project from the 1970s.

	OWL Web Ontology Language 1.0 Abstract Syntax
		The W3C Web Ontology Working Group (WebOnt) is tasked with producing a web ontology language extending the reach of XML, RDF, and RDF Schema.
		An OWL ontology is a sequence of axioms and facts, plus inclusion references to other ontologies, which are considered to be included in the ontology.
		Ontologies also have a non-logical component (not yet specified) that can be used to record authorship, and other non-logical information associated with an ontology.

		Web Services are the proper means for accessing semantically enriched data, and semantically-enabled Web Services are essential to providing the mature and scalable operating conditions necessary for their successful deployment in stable and secure environments.
		This WG was chartered as part of the W3C Semantic Web Activity to "focus on the development of a language to extend the semantic reach of [the then-] current XML and RDF meta-data efforts.
		A further necessity is for such languages to be based on a clear semantics (denotational and/or axiomatic) to allow tool developers and language designers to unambiguously specify the expected meaning of the semantic content when rendered in the Web Ontology syntax.

	OWL Web Ontology Language Reference
		The Web Ontology Language OWL is a semantic markup language for publishing and sharing ontologies on the World Wide Web.
		The complete OWL language (called OWL Full to distinguish it from the subsets) relaxes some of the constraints on OWL DL so as to make available features which may be of use to many database and knowledge representation systems, but which violate the constraints of Description Logic reasoners.
		This identifies the specified ontology as a prior version of the containing ontology, and further indicates that it is backward compatible with it.

	Cover Pages: W3C Releases Candidate Recommendations for Web Ontology Language (OWL).
		An emerging ontology standard designed to strengthen the Semantic Web foundations, OWL is "a language for defining structured, Web-based ontologies which enable richer integration and interoperability of data across application boundaries.
		Ontologies are used by people, databases, and applications that need to share subject-specific (domain) information -- like medicine, tool manufacturing, real estate, automobile repair, financial management, etc. Ontologies include computer-usable definitions of basic concepts in the domain and the relationships among them.
		OWL is already being used as an open standard for deploying large scale ontologies on the Web." The six Candidate Recommendation documents for OWL are written for different audiences, addressing variable needs in understanding and implementing the OWL language.

	The benefits of the Web ontology language in Web applications
		The next element required for the Semantic Web is the OWL Web ontology language (OWL), which can formally describe the semantics of classes and properties used in Web documents.
		Of course, such a technique relies on content providers annotating their pages with the Web ontology language, but if you assume that these owners will try to distribute their content as widely as possible, it seems that they may be willing to do this.
		Another common use of this kind of ontology is to support the visualization and editing of charts that show snapshots of the information space centered on a particular concept (e.g., a class or instance).

	OWL flies as Web ontology language \| InfoWorld \| News \| 2003-08-19 \| By Paul Krill (Site not responding. Last check: 2007-10-13)
		The World Wide Web Consortium (W3C) on Tuesday issued its Web Ontology Language, its acronym spelled and pronounced "OWL," as a W3C Candidate for Recommendation, meaning the organization is seeking more implementations of the language.
		According to the W3C, OWL is a language for defining structured Web-based ontologies that enable richer integration and interoperability of data across application boundaries.
		While earlier languages have been used to develop tools and ontologies for specific user communities such as sciences, they were not compatible with the architecture of the World Wide Web in general, in particular the Semantic Web, said W3C.

		The objective of the Semantic Web architecture is to provide machine processing of web information on a global scale.

		Here the interpretations of the Web Ontology Language would be RDF interpretations, with extra semantic conditions providing the meaning of the additional constructs, just as the model theory for RDFS is.
		Here the interpretations of the Web Ontology Language would be similar to RDF interpretations, but there would be differences, perhaps in the treatment of certain kinds of classes.
		The model theory of the Web Ontology Language might sanction the inferences involving classes or other constructs that do not show up in a knowledge base.

		First, the author presents a brief history of the web and explains the concept of the "semantic web." In order to have computers understand web contents and do the corresponding processing of the understood information, such contents cannot be within HTML or XML tags that are only human-understandable.
		Such ontologies are machine-understandable definitions of the concepts and how those concepts are related in the relevant field(s).
